Abstract
A test device and method for determining the presence of a component in a sample are disclosed, as well as a method for making the device. The device utilizes a reactant system which produces a detectable response upon contact with the sample component, the reactant system being incorporated with a carrier matrix. The carrier matrix comprises separate filaments formed into a cloth. At least one ingredient of the reactant system is incorporated with some of the filaments prior to their being formed into the cloth. The method for making the device comprises interweaving the filaments bearing at least one reactant ingredient into a warp of other filaments, knitting the filaments into a cloth, forming a mat cloth of randomly oriented filaments or affixing the filaments to a matrix support member in a substantially parallel orientation.
